Beatskillz and Stagecraft have released Loopbazaar, a cloud based "loop browser" plugin that lets you audition and find thousands of royalty free loops and samples from various labels and producers.

You can search for loops/samples by search term, key, genre, BPM, style etc. The loops can be synced to your DAW tempo and tested before you buy, you can also buy Loop and Sample Packs directly from this plugin, without ever leaving you DAW and workflow.
